Mine was legitimate, and no the cops cannot ticket you for tint if you have a prescription for it. I've been asked about my tint once I had the script, show the cop and he was "OK cool" and didn't say another word.
Simply you need to talk to your eye doc about it, if you don't have eye problems that warrant it, it's probably not gonna happen. I have extreme sensitivity to light as well, I just don't get hassled enough to worry about it.
Light sensitivity is one reason, or any other kind of eye condition that would worsen or make driving more difficult if you encounter glare.
For example, I have a condition called nystagmus. Basically, it means that I have limited depth perception and my eyes have difficulty locking on to and following an object. (If I watch golf -- even on TV -- I can't follow the ball in the air, I just lose it. About the smallest object I can follow is a softball, and that's only if it's neon green so it has some contrast.) The glare from the sun or cars' headlights exacerbates this for me. Polarized prescription sunglasses have helped, but I'm not wearing sunglasses at dusk/dawn or at night. Tint is polarized, though, so it does a great job of knocking down the glare regardless of the time of day.
But yes, you need to discuss this with your eye doctor.
nope. no note whatsoever. I usually park in the same spot tues & thurs so i'm going to keep an eye out for a blue car with a scratched bumper, maybe get some info or leave a note for them or something. Completely ruined my day.
